Dholes produce whistles resembling the calls of red foxes, sometimes rendered as
coo-coo. How this sound is produced is unknown, though it is thought to help in coordinating the pack when travelling through thick brush. When attacking prey, they emit screaming
KaKaKaKAA sounds. Other sounds include whines (food soliciting), growls (warning), screams, chatterings (both of which are alarm calls) and yapping cries. In contrast to wolves, dholes do not
howl or bark.
Social and territorial behaviour Dholes are more social than
gray wolves, They live in
clans rather than
packs, as the latter term refers to a group of animals that always hunt together. In contrast, dhole clans frequently break into small packs of three to five animals, particularly during the spring season, as this is the optimal number for catching fawns. Dominant dholes are hard to identify, as they do not engage in dominance displays as wolves do, though other clan members will show submissive behaviour toward them. Clans typically number 5 to 12 individuals in India, though clans of 40 have been reported. In
Thailand, clans rarely exceed three individuals. and domestic dogs. They may defecate in conspicuous places, though a territorial function is unlikely, as
faeces are mostly deposited within the clan's territory rather than the periphery. Faeces are often deposited in what appear to be communal
latrines. They do not scrape the earth with their feet, as other canids do, to mark their territories. Like
African wild dogs and
dingoes, dholes will avoid killing prey close to their dens. The
gestation period lasts 60–63 days, with litter sizes averaging four to six pups. Pups are suckled at least 58 days. During this time, the pack feeds the mother at the den site. Dholes do not use
rendezvous sites to meet their pups as wolves do, though one or more adults will stay with the pups at the den while the rest of the pack hunts. Once
weaning begins, the adults of the clan will regurgitate food for the pups until they are old enough to join in hunting. They remain at the den site for 70–80 days. By the age of six months, pups accompany the adults on hunts and will assist in killing large prey such as
sambar by the age of eight months. Maximum longevity in captivity is 15–16 years. Dholes are primarily
diurnal hunters, hunting in the early hours of the morning. They rarely hunt at night, except on moonlit nights, indicating they greatly rely on
sight when hunting. They can chase their prey for many hours. When chasing fleet-footed prey, they run at a pace of . (
Rusa unicolor),
Bandipur National Park Once large prey is caught, one dhole grabs the prey's nose, while the rest of the pack pulls the animal down by the flanks and hindquarters. They do not use a killing bite to the throat. They occasionally blind their prey by attacking the eyes.
Serows are among the only ungulate species capable of effectively defending themselves against dhole attacks, due to their thick, protective coats and short, sharp horns capable of easily impaling dholes. Prey weighing less than is usually killed within two minutes, while large stags may take 15 minutes to die. Once prey is secured, dholes tear off pieces of the carcass and eat in seclusion. They give the pups access to a kill. They are generally tolerant of
scavengers at their kills. Both mother and young are provided with regurgitated food by other pack members. There is one record of a pack bringing down an
Indian elephant calf in
Assam, despite desperate defense of the mother, resulting in numerous losses to the pack. Dholes eat
fruit and
vegetable matter more readily than other canids. In captivity, they eat various kinds of grasses, herbs and leaves, seemingly for pleasure rather than just when ill. In summertime in the Tian Shan Mountains, dholes eat large quantities of mountain
rhubarb.
Livestock predation by dholes has been a problem in Bhutan since the late 1990s, as domestic animals are often left outside to graze in the forest, sometimes for weeks at a time. Livestock stall-fed at night and grazed near homes are never attacked.
Oxen are killed more often than
cows, probably because they are given less protection.
Enemies and competitors , India In some areas, dholes are
sympatric to
tigers and
leopards. Competition between these species is mostly avoided through differences in prey selection, although there is still substantial dietary overlap. Along with leopards, dholes typically target animals in the range (mean weights of for dhole and for leopard), while tigers selected for prey animals heavier than (but their mean prey weight was ). Also, other characteristics of the prey, such as sex, arboreality and aggressiveness, may play a role in prey selection. For example, dholes preferentially select male chital, whereas leopards kill both sexes more evenly (and tigers prefer larger prey altogether), dholes and tigers kill
langurs rarely compared to leopards due to the leopards' greater arboreality, while leopards kill wild boar infrequently due to the inability of this relatively light predator to tackle aggressive prey of comparable weight. Tigers are dangerous opponents for dholes, as they have sufficient strength to kill a dhole with a single paw strike. Dhole packs are smaller in areas with higher tiger densities due to tigers directly killing dholes and stealing kills they made. The kleptoparasitism causes dholes to prefer hunting smaller animals because they can eat more of a smaller carcass before a tiger arrives to steal it. Direct predation can lead to lower reproductive and recruitment rates, lower hunting success rates and less food for the pups when a helper is killed, and potentially pack destabilization if one member of the breeding pair is killed. Dhole packs may steal leopard kills, while leopards may kill dholes if they encounter them singly or in pairs. Dholes were once thought to be a major factor in reducing
Asiatic cheetah populations, though this is doubtful, as cheetahs live in open areas as opposed to forested areas favoured by dholes. Since leopards are smaller than tigers and are more likely to hunt dholes, dhole packs tend to react more aggressively toward them than they do towards tigers. Dhole packs occasionally attack
Asiatic black bears,
snow leopards and
sloth bears. When attacking bears, dholes will attempt to prevent them from seeking refuge in caves and lacerate their hindquarters. The dhole is also sympatric with the
Indian wolf (
Canis lupus pallipes) in parts of its range. There is at least one record of a lone wolf associating with a pair of dholes in
Debrigarh Wildlife Sanctuary, and two observations in
Satpura Tiger Reserve. They infrequently associate in mixed groups with
golden jackals. Domestic dogs may kill dholes, though they will feed alongside them on occasion.
Diseases and parasites Dholes are vulnerable to a number of different diseases, particularly in areas where they are
sympatric with other canid species. Infectious pathogens such as
Toxocara canis are present in their faeces. They may suffer from
rabies,
canine distemper,
mange,
trypanosomiasis,
canine parvovirus and
endoparasites such as
cestodes and
roundworms. ==Threats==
